Locate the rectangle on the next page. This is going to be your picture plane.
Make the scale measurements around the rectangle. Make every ½ inch represent one foot. How big is the room??
About how tall are you? Draw a straight line parallel to the floor of the picture plane at your height. (It is ok to round to the nearest foot or half foot on your height). Call this line the eye level line.
On the eye level line, close to the right hand side of the square, choose a central vanishing point. Make a dot and label it CVP.
Using your ruler, draw straight lines from every corner of the rectangle to your CVP.
Now measure 8 feet to the left of your CVP and make a dot. Label this point SVP for special vanishing point.
Using your ruler, draw a straight line from the 6 foot mark on the floor to the SVP. The point where this line meets the diagonal from the lower left corner of your rectangle to the CVP will be the back left corner of your room. You can now draw the back wall of your room, you get a corner every time you meet up with a diagonal to the CVP.
You can now construct the perspective floor grid. Draw straight lines from the measurements marked along the floor line to the CVP, but stop at the back wall of your room.
Draw straight lines from the measurement marks 1-5 along the floor to the SVP. Now, where these new lines cross the stripes on the floor, make lines parallel to the floor line. These are the horizontal stripes on the floor. You have made the floor grid.
Now, all you have to do is put in the cube as specified in this floor plan diagram and elevation chart.
Good luck! Ask for help if you need it.
Now for even more challenge, put in the cube explained in the following floor plan and elevation charts. Hint: You will need another SVP the same distance from the CVP as the other one, but in the opposite direction.
13. What else can you put into your perspective room? Some windows? Something that isn’t a cube? Ask for help if you need it!
